I went to Canadian Tire and I purchased a set that contained two neons and a sensor which allows you to adjust the sensitivity to which they beat to from the music.

Originally the kit powered into the cigarette lighter so I had to rewire it and hook it up to the power source for the lights. They run under the mats and they're attached underneath my seat so they're out of view but you see them flash up the entire cab with a sweet-looking blue glow to the same beat as my hip hop music.

I just wish they were brighter...

Anyway, how old are you? You look about my age in your user gallery. I'm 18.
